More InformationTranscript It's time again for another video quiz from Access Learning Zone.
Today's quiz is for expert-level users. There are five questions, and they're going to come fast. I'm only going to give you a few seconds to answer each one, so hit the pause button if you need it. Keep track of your score, and we'll see how you did at the end.
Are you ready? Here we go.
Question 1. What is the usual purpose of a foreign key field in an Access table? To identify every record in that same table, to store a reference to a related record in another table, to automatically calculate totals for a record, or to prevent users from editing the table.
That is B, to store a reference to a related record in another table. That's a foreign key.
Question 2. What does an inner join in an Access query normally return? Every record from both tables, matched or unmatched, only records that have matching values in both join tables, every record from the first table only, or only records with blank join fields.
That's going to be B, only records that have matching values in both join tables. That's an inner join.
Question 3. You want to see every customer, including customers who have never placed an order. Which join is most appropriate? An inner join from customers to orders, a left join that includes all customers' records, a join using only the orders' primary key, or no join because related data cannot appear in one query.
That'll be a left join that includes all customers' records.
Question 4. When a query displays customer fields beside order fields, what usually happens to the underlying table data? Access permanently copies the customer data into the orders table. Access deletes duplicate customer records automatically. Access displays related data together without duplicating it in the tables, or Access converts both tables into one new table.
That'll be C, Access displays related data together without duplicating it in the tables.
And question 5. In Access, why might a query unexpectedly show an Enter Parameter Value box for a field name? The query is asking Access to create a new table. Access cannot find a field or control name referenced by the query. The primary key contains duplicate values, or the query has too many records to display.
This one comes up all the time. It's B, Access can't find a field or control name referenced by the query. Usually, it's a misspelling.
All right, how'd you do? Did you get all five right? Are you the chancellor of the high council, or did your trouble win the duel?
If you missed any of these topics, more are covered in my Access Expert Level 1 class, Lesson 3, on relational queries.

Summary In today's Video Quiz, I have five expert-level Microsoft Access questions for you. The questions cover foreign keys, joins, relational queries, and a common cause of unexpected parameter prompts. Keep track of your answers and see how well you do.
Question 1: What is the usual purpose of a foreign key field in an Access table?
A foreign key stores a reference to a related record in another table. For example, an Orders table may contain a CustomerID field that identifies which customer placed each order. The CustomerID in the Orders table is the foreign key because it refers to the primary key in the Customers table.
Question 2: What does an inner join in an Access query normally return?
An inner join returns only records where matching values exist in both tables involved in the join. For example, if you join Customers to Orders with an inner join, you will only see customers who have at least one matching order. Customers without orders will not appear in the results.
Question 3: You want to see every customer, including customers who have never placed an order. Which join is most appropriate?
Use a left join that includes all records from the Customers table. This type of join shows every customer, whether or not there is a related order record. Customers with no orders will still appear, but their order fields will be blank.
Question 4: When a query displays customer fields beside order fields, what usually happens to the underlying table data?
Access displays related information together in the query results without copying or duplicating the data in the underlying tables. The Customers and Orders tables remain separate. The query simply combines the information for display based on the relationship between the tables.
Question 5: Why might an Access query unexpectedly display an Enter Parameter Value box for a field name?
This usually happens because Access cannot find a field name, control name, or other reference used in the query. In most cases, the name was misspelled, changed, deleted, or referenced incorrectly. Access assumes that an unrecognized name is a parameter and prompts you to enter a value.
If you got all five questions right, excellent work. If you missed any, these concepts are covered in more detail in my Access Expert Level 1 course, Lesson 3, which focuses on relational queries.
